1963 Ford Falcon Sprint, 260 and 4 speed. I cannot shift to 3rd & 4th gear. Stock shifter has been replaced sometime in the past with an aftermarket Hurst. Crawled under the hood and saw the linkage for 3rd/4th has been cut and rewelded. Anyone know a way to determine if this was done wrong? And where I can order a stock shifter with linkages so I can swap all of it out? Thanks.
